That's correct. We're hearing from just about everyone, including the duke and duchess of cambridge. They were the guest of honor at the london premiere of "man della: The long walk to freedom." It was taking place when the news broke. Prince william expressed his sympathies, as he left the screening with kate by his side. It's extremely sad and tragic news. We minded what an extraordinary man mandela was. And my thoughts and prayers are with his family. The irony of the timing. The film's producer announcing the news at the screening. And a moment of silence was held after the final credits rolled. We're hearing from peter gabriel. He was one of the celebrities to work with nelson mandela. He counted him as a friend. Speaking from new york, gabriel put forward a challenge to continue nelson mandela's legacy. The end ofan anneer ra. And I hope that today's leaders and politicians. And there will be people big enough to step into his shoes. Peter gabriel worked with mandela on human rights causes. And played at a birthday concert when mandela turned 70. And lionel richie tweeting this photo of himself and the leader. Saying, your legacy and strength will live on forever. It's not well-known. But lionel richie was a stylist for nelson mandela when he first arrived in the united states, of n 1990. His wardrobe was a little out of date there. As richie put it, his job was to make the clothing work. Richie was joined by other entertainers. I never heard that before. Quincy jones made sure mandela had what he needed during that historic trip to the united states.
